JOURNAL AND BOX.

SPECIFICATION forming part of Letters Patent No. 537,059, dated April 9, 1895.

' Application an May 31,1894. Serial No 512,984.. (No model.)

To will whom it may concern:

Be it known that I, ISBON METZGER, a citizen of the United States, residing in the county of Louisa, near Winfield, and State of Iowa, have invented certain new and useful Improvements in Journals and Boxes or Bearings Therefor, of which the following is a full, clear, and exact specification.

My invention relates to improvements in journals of axles or shaftings and the boxing or bearings therefor, and it is more articularly designed as an improvement on the invention covered by United States Letters Patent No. 511,445, granted to me December 26, 1893, to which reference may be had for an understanding of features common to both devices not fully described herein.

The primary object of my present invention is to still further reduce the liability of the oil splashing or running out of the journal box around the shaft or axle, and at other places, and to prevent the sand and grit from entering the box. 7

Another object of myinvention is to simplify and improve the means of holding and adjusting the abutment for limiting the end thrust of the axle or journal.

Wit-h these'ends in view my invention consists in certain features of novelty'iu the construction, combination and arrangement of parts hereinafterd'escribed with reference to the accompanying drawings, and morepar' ticularly pointed out in the claims.

In the said drawings, Figure 1 is a plan view. of a car axle box wheel and journal, showing the upper half or section ot' the box removed.

Fig. 2 is. a longitudinal section thereof taken lengthwise of the axle, the upper half of the box being in place; Fig. 3 is a'vie'w looking. at the inner end of the box, showing the opening therein forthe passage of the shaft or axle,- the latterbeing removed. Fig.4 isa plan view of the lower. half of the box showing a modified form of means for holding the abutment in place. Fig. 5 is a detail sectional view taken on the line 5-5 Fig. 4. Fig. 6 is a vertical longitudinal sectional view of a part of the box taken through the door therein, showing the preferred form of means for seal- I ing the int'erstice between such door and the. edge of the opening. Fig. 7 is a sectional. view thereof taken on the line 77 Fig. 6. Fig.8

is a view similar to Fig. 6 with the door removed,'and Fig. 9 is amodified form of a journal or axle hereinafter described, partly in section and partly broken away.

Like signs of reference indicate throughout the several views.

- In constructing my axle or journal so as to prevent the oil from working or splashing out through the axle opening in the box, 1 proceed upon'the principle that a liquid while on a rotating body will be driven by the centrifugal force to its largest diameter before entirely leaving it. Hence I provide the axle or shaft at the opening in the box with a number of conical or flaring flanges which like parts have their largest diameters arranged nearfinds its way upon these flanges will be driven by the centrifugal force to the larger edge of the flange before it drips off; and in combination with the axle thus formed I so form the edge of the opening in the box as to catch the oil as it flies from the larger edge of the flange, and convey it back to the oil well, the inner edges of the flanges being formed at an abrupt angle to the shaft so that they will not defeat the purpose of the invention by driving the oil toward the box opening. v

Referring now more particularly to Figs. 1,

2 and 3, 1 is the lower half and 2 the upper .axle or shaft projects. .The lower half of this box'constitutes an oil well in which the enlarged journal 3' dips, as shown in Fig. 2.

That portion of the axle 4 which projects into the box from the outer side of the wheel 5 is formed integrally with or, otherwise socured to the enlarged journal and between the enlarged journal3 and the wheel, it is provided next the wheel with an enlarged flange 6 which is inclosed by a hood or groove 7 formed in the upper and lower halves of the box. The purpose of this flange is to arrest the grit and sand that might otherwise find their way into the box, and to the end that the groove at the lower side of the box may notretain such grit and sand as collect upon the upper side of the axle and fall into the groove, the lower half of the groove is cut away as shown at '8 in Figs. 2 and 3, so that the grit carried around by-the axle will be dumped cit into the groove and then slide out of the latter. Between the flange 6 and the journal 3 the axle is formed with a coni- 5 cal flange 9 whose larger diameter is located on the side next the journal 3; and on each side of the flange 9 is formed another flange 10, 11, respectively, which also flare in the same direction as the flange 9, that is to say, to their larger diameters are arranged on the inner side or side next the journal 3. By this means a catch groove is constituted on each side of the flange 9 and also a groove or reduced portion 12 is formed between the inner I5 edge of the flange and the journal 3.

The upper edge of the box immediately over the edge of the flange 10 is: rovided. with a depending portion whose lower edge is triangular or A-shaped in cross section so as to form a depending or drip point. 13; immediately over the reduced portion 12am d another drip point 14: between the flange 9 and the edge of the flange 1:0. Thusit will be seen-that any oil which might splash upward against the under side of the portion 12' will be arrest-ed by the abrupt edge of the fl'angelO; and that portion of theoilwhich is carried up by the flan gelO by the cen trifugal force will be driven against the under side of the said A-shaped 3o portion whence it will drip from the point 13 back upon the portion 12 andthence nuninto the oil well. Any excess ofi oil which gets upon the flange 1O andrunstoward the flange 9. will? be arrested by the latter, and collecting 5 in the groove constituted by these two flanges will drip ott from the under side of the axle onto the incline surface 15 formed in the lower half oh the opening in the box,.which will lead the oil to a duct 16 extending back into the oil well. The lowerinner side of this incline 15 is bordered by an abrupt wall 17 which stands above the lower edge of the flange 9 so as to prevent the oil from splashing. directly up onto the incline 15; and the upper edge of the wall 17 is also inclined toward the latter immediatel under the larger edge of the flange 10 so as to catch the drippings from such flange and convey the same back into the well.

Any oil which finds itsway to the periphery of the flange 9 will either drip ofi onto the incline 15 and run back into the well,.or else it will be thrown by centrifugal force to the larger edge of the flange 9 and? if it leaves such edge, will strike upward against-the top of a recess l8 which is A-shaped in cross section andarrangedimmediately over the flange 9 so as to constitute a drip point on either side of such flange, one of such points being the same as the point 14, the other being indicated at 19. The oilhowever which flies from the edge of the flange 9 will strike against the inner side of the recess 18 and. consequently run down to the point 14 and drip oflf onto the flange 10, whenceitwillieit her run down upon the inclines 15 or 17 or else be thrown up and drip off of the drip point 13-back outothere duced portion 12 and thence into the oil well. The upper edge of the opening in the box is also provided immediately over the larger edge of the flange 11 with a depending portion whose lower edge is A-shaped in cross section so as to constitute on the outer side a drip point 20 and on the inner side an inclined surface leading to the drip point 19 which latter is immediately over the groove consti tuted by the flangess 911. The purpose of the drip point 19 it will be seen is to catch any oil which might be thrown upward by the flange 11 and drip it off into the groove between such flange and the flange 9 whence it will be cast upon the incline 15 which extends out under the flange 11'. The purpose of the point 20 is more for arresting the passage of grit which might find its way over the edge of the flanged and strike downward toward the groovebetwecn the flanges 9l1, it being observed'that the point 20 intercepts a straight line between the edge of the flange 6 and the inner edge of the flange 11. By this means the grit which finds its way over the edge of the flange 6 will be cast downward upon the flange L1 and will slip olf either through the opening 8 or else on-tot'he'incline 15, and if on the latter itwill be washed by the oil back into 95 thebottourof the oil well where it will not affect thejourn-al.

Arranged above the enlarged journal 3 is a bushing or hearing. block 2t whose upper side is rounded as shown in Fig. 2 in order that the journal may rock in a vertical plane independently 06 the box without losing perfeet contact with the bushing. This bushing or block 21 is held in place by means of a transverse bolt or bar 22 which passes athwart the upper half of the bore at the end of the bushing.

23 is the abutment for limiting the end thrust of the journal or axle. This is preferably made revolnble and consists of the enlarged end or head against which the journal abuts, and a tapering end 24 which is arranged in a conical socket formed in a cross head 25, the parts being so proportioned. that the enlarged head at the outer end will have a bearing against the side of. the cross head while the conical sides of the portion 24: and the inner end ofsuch portion will bear against the side and end respectively of the socket in the cross head"; thus equally distributing the friction and reducing the wear. The in ner end of the portion 24: is provided with a stem 26 which passesthrough the cross head and carriesta nut; 27 whereby the revoluble abutment and crosslhead are secured together in such a manner that the former may revolve with the journal. The end of the enlarged journal 3 is provided with a projection 28 which is of the same diameter asthe opposing end of theabutment 23. The purpose of this is to prevent the abutment from wearing. a cavity in the end of the journal, which, when the journal made lateral movements independently of the box, would strains and probably damage the parts. The ends of the cross he'ad25 are supported upon two blocksor lugs; 29 arrangedon opposite sides of the lower-half of the box; and such cross head is held up to its work so as to rigidly resist the end thrust of the axle, by means of two screw rods 30 which pass through the inner end of the box and also through the ends of the cross head and carry, on the off-side of the cross head, the nuts 31 by means of which the cross head with its abutment may be adjusted toward the journal. Ordinarily however, the abutment is so adjusted as to be normally out of contact with the journal, but in close proximity to it so that the slightest end thrust will be resisted while the great friction which would result from continuous contact, is avoided.- Located on the rods 30 between the inner end of the box and the ends of the cross head are coil springs 32 whose purpose is to hold the abutment normally away from the journal while at the same time permitting the abutment to be adjusted toward the journal by simply manipulating the nuts 31, the latter being provided with projections 33 which engage with pins, 34 for locking them.

35 is the door-way of the box through which access to the interior of the box may be had; This door-way is preferably closed by means of the construction shown in Figs. 6,7and 8. In this form the edge of the box-around the door-way 35 is provided with a rib-or feather 36 which extends around its lower edge and also its two side edges. The door 37 is preferably constructed of a piece of sheet metal having a groove complementary in shape to the rib 36, formed in its lower side so that when the door is in position such groove will between the head thereof andthe under side of the box, is a'spring 39which permits of longitudinal movement of the bolt while hold- .ing it normally inward. This provides for the door 37 being raised at its lower edge so as to disengage the groove therein with the rib 36 and thereby permit the door to be turned to one side for uncovering the opening 35. To the end that the rib 36 may not interfere with this movement of the door the portions of such 'rib which are at the sides are tapered toward their upper ends as shown in Fig. 8.

In Fig. 4, which shows a modified form of means for holding the abutment'aud cross head, the lower half of the box is provided with a support 40 upon which the reduced ends 41 of the cross head 25 rest and slide. At each end of each of these supports 40 is formed a shoulder 42' and between these when-it is dcsired to adjust the cross head, it is only necessary to remove a block from one side and place it on the other side of the end 41. By making the blocks of different thicknesses I am enabled to effect the nice adj ustment of the cross head by exchanging the blocks on one side for those on the other.

The ends 41 of the cross head are slightly rounded as shown in Fig. 4, and the blocks 43, 44 are of such thickness as to leave a slight play between them and the ends of the cross head, whereby the cross head may oscillate on a vertical axis so that the abutment will remain squarely against the end of the journal, notwithstanding the lateral movement of the latter with reference to the box when rounding curves.

The blocks 43, 44 and'cross head are held against vertical displacement by means of end of the bar 45, while the other end of the bar is secured by means of abolt 48 passing through it and the other shoulder 42.

In the modified form of axle or shaft shown in Fig. 9 the enlarged journal 3 and the larger ones 9 10 of the'conical flanges are formed separat'elyfrom jtheshaft or axle. This may be best done by first shrinking upon' the inner end of the axle 4 a sleeve of sufficient length to constitute both the journal 3 and'the flanges 9 10 After this is done the sleeve is turned down preferably until the as shown in Fig. 5, for the introduction of the ICO between the edge of the flange 10 and the journal; and the flanges 9 1O are also formed by turning down the sleeve as will be understood, the flange 9 on the outer side being slightly rounded instead of straight like the edge of the flange 9 before described, for the purpose of giving greater body .to its outer edge and avoiding breakage. The axle or journal on the outer side of the flange 9 is then turned down to form the flange 11 and thus constitute a groove between the latter flange and the flange 9" as shown. The flange 11 is conical with its larger edge turnedtoward the journal, and between the flange 11 and the exterior of the box is formed an additional flange 6 whose outer edge borders on a groove 49 into which the sand and grit are caught and tilted out on the underside,

the edge of the box immediately under such groove being beveled as at 8 so as to avoid catching the grit as it falls; and from the upper edge of this bevel 8 the edge of the box in the lower half ofthe opening is beveled inward and downward so as to convey the oil back into the oil well. The last mentioned bevel however is provided with a swell. 50 which extends above a straight line drawn between the lower edge of the flange 6 and the lower edge of the flange 9 so as to intercept the direct passage of grit and dust into the box. The flange 6 is of considerable less diameter than the main portion of the axle 4 whereby the shoulder4 is constituted which overlaps the edge of the opening in the box and thus intercepts the direct passage of grit into the box over the flange 6 The upper edge of 'the 0 enin over the flan e 9 in this form of I s a the invention may be substantially complementary in shape to the edge of the flange, but in both the forms the drip points 14: and 19 are constituted on both sides of the flange. The edge of the box opening over the flange 6 in this form is shown as A -shape in cross section the purpose of which is the same as that of the groove or recess 7 in the form first described.

While I have been particular to describe the minute details of construction of the devices shown, it will nevertheless be understood that I do not limit myself to the same as they might be omitted or varied at pleasure withoutdeparting from the spiritof theinvention.
